我们提出了一个逆向设计工具的织物模板-一个过程中，平板缝在一起，形成一个织物容器铸造石膏雕塑。与3D打印技术相比，织物模板的好处是其低成本和易于运输的特性。织物模板的过程类似于模制和铸造，但具有软边界。织物容器的变形由来自液体填充的压力和拉伸织物中的张力之间的力平衡控制。制造的最终结果取决于平板的形状、制造方向和外部支撑的放置。我们的计算框架生成优化的平板和制造方向参考目标形状，并确定外部支持的有效位置。我们展示了这个设计工具的功能，在各种不同的形状和拓扑结构的模型。物理制造也被证明，以验证我们的方法。
We present an inverse design tool for fabric formwork - a process where flat panels are sewn together to form a fabric container for casting a plaster sculpture. Compared to 3D printing techniques, the benefit of fabric formwork is its properties of low-cost and easy transport. The process of fabric formwork is akin to molding and casting but having a soft boundary. Deformation of the fabric container is governed by force equilibrium between the pressure forces from liquid fill and tension in the stretched fabric. The final result of fabrication depends on the shapes of the flat panels, the fabrication orientation and the placement of external supports. Our computational framework generates optimized flat panels and fabrication orientation with reference to a target shape, and determines effective locations for external supports. We demonstrate the function of this design tool on a variety of models with different shapes and topology. Physical fabrication is also demonstrated to validate our approach.
